;; "C-s" does an incremental search forward (e.g. - as each key is ;; the search string is entered, the source file is searched for the ;; first match. This can make finding specific text much quicker as ;; you only need to type in the unique characters. Repeat searches ;; (using the same search characters) can be done by repeatedly ;; pressing "C-s" ;; "C-r" does an incremental search backward ;; "C-s RET" and "C-r RET" both do conventional string searches ;; (forward and backward respectively) ;; "C-M-s" and "C-M-r" both do regular expression searches (forward ;; and backward respectively) ;; "M-%" does a search/replace while "C-M-%" does a regular ;; expression search/replace
